camera number

Select one of the optical telescope cameras for optical pointing.

Mandatory Arguments:
Camera number
The number of the camera to be selected.

Example:
The following example tells the tracker to switch on the primary optical pointing camera along with its optical pointing model.
 camera 0

Context:
The CBI telescope possesses a number of optical telescopes with accompanying optical cameras. These are mounted on different parts of the telescope to allow us to see if the measured optical pointing model depends on local distortions or is global to the telescope mount. When a new camera is selected, its output is displayed on the camera monitor in the control room and its optical pointing model is selected. Note that the flexure, encoder zero points, and the model tilts are common to both the optical and radio pointing models, so switching cameras also effects radio pointing. The TV angle, used by the cbiviewer optical-pointing window, and the tv_offset command, is also dependent on the camera, so the appropriate angle is switched in along with the camera. See the documentation of the tv_angle command for how to set this up individually for each camera.
